Harvest Moon by Robyn Carr

Rising sous-chef Kelly Matlock's sudden collapse at work is a wake-up call. Disillusioned and burned out, she's retreated to her sister Jillian's house in Virgin River to rest and reevaluate.
Puttering in Jill's garden and cooking with her heirloom vegetables is wonderful, but Virgin River is a far cry from San Francisco. Kelly's starting to feel a little too unmotivated…until she meets Lief Holbrook. The handsome widower looks more like a lumberjack than a sophisticated screenwriter—a combination Kelly finds irresistible. But less appealing is Lief's rebellious stepdaughter, Courtney. She's the reason they moved from L.A., but Courtney's finding plenty of trouble even in Virgin River.
Kelly's never fallen for a guy with such serious baggage, but some things are worth fighting for. Besides, a bratty teenager can't be any worse than a histrionic chef…right?
